Important Safety Considerations
Leukine® is contraindicated in patients with excessive leukemic myeloid blasts in bone marrow or peripheral blood (≥ 10%), in patients with known hypersensitivity to GM-CSF, yeast derived products or any component of Leukine, and for concomitant use with chemotherapy and radiotherapy.

Transplantation of Peripheral Blood Progenitor Cells (PBPCs)

Leukine® (sargramostim) is indicated for use in mobilization and following transplantation of autologous PBPCs. In this retrospective efficacy study, mobilization and myeloid reconstitution of 4 groups of Leukine patients (n=196) from a single institution were compared with 100 historical controls treated at the same institution who did not receive any mobilization treatment, and to an autologous historical bone marrow transplant group. The study groups receiving Leukine differed by dose (125 or 250 mcg/m2/day) and administration route (IV over 24 hours or subcutaneous injection).

Leukine was well tolerated and effective for mobilization of PBPCs before and during leukapheresis of cells for transplantation. Leukine increased the number of progenitor cells and myeloid recovery after PBPC transplantation. Leukine decreased days to neutrophil recovery, days to last red blood cell (RBC) transfusion, days to last platelet transfusion, days to engraftment, and days of hospitalization. Leukine did not adversely affect relapse rate or survival. The detailed results are provided below.

The most marked mobilization and post-transplant effects were seen in patients administered the higher dose of Leukine1:

  • Mobilized patients had fewer days to the last platelet transfusion and last RBC transfusion, and a shorter duration of hospitalization, than did non-mobilized patients
  • Liquid solutions containing benzyl alcohol (including liquid Leukine) or lyophilized Leukine reconstituted with Bacteriostatic Water for Injection, USP (0.9% benzyl alcohol) should not be administered to neonates

Indication

Leukine® is indicated for the following uses: (i) following induction chemotherapy in older adult patients with acute myelogenous leukemia (AML) to shorten time to neutrophil recovery; (ii) for mobilization and following transplantation of autologous peripheral blood progenitor cells; (iii) for myeloid reconstitution after autologous or allogeneic bone marrow transplantation (BMT); (iv) for use in bone marrow transplantation failure or engraftment delay.

Important Safety Considerations

  • Leukine is contraindicated in patients with excessive leukemic myeloid blasts in bone marrow or peripheral blood (≥10%); in patients with known hypersensitivity to GM-CSF, yeast-derived products, or any component of Leukine; and for concomitant use with chemotherapy and radiotherapy.
  • Serious allergic or anaphylactic reactions have been reported with Leukine. If any serious allergic or anaphylactic reactions occur, Leukine therapy should be immediately discontinued and appropriate therapy initiated.
  • Liquid solutions containing benzyl alcohol (including liquid Leukine) or lyophilized Leukine reconstituted with Bacteriostatic Water for Injection, USP (0.9% benzyl alcohol) should not be administered to neonates.
  • Leukine should be used with caution and monitored in patients with preexisting fluid retention, pulmonary infiltrates, or congestive heart failure, respiratory symptoms or disease; cardiac symptoms or disease; and renal or hepatic dysfunction.
  • Edema, capillary leak syndrome, pleural and/or pericardial effusion, sequestration of granulocytes in the pulmonary circulation, and dyspnea have been reported in patients after Leukine administration. Occasional transient supraventricular arrhythmia has been reported during Leukine administration. Leukine has induced the elevation of serum creatinine or bilirubin and hepatic enzymes in some patients. Monitoring of renal and hepatic function in patients with preexisting renal or hepatic dysfunction is recommended at least every other week during Leukine administration.
  • Adverse events occurring in >10% of patients receiving Leukine in controlled clinical trials and reported in a higher frequency than placebo were: in AML patients – (fever, skin reactions, metabolic disturbances, nausea, vomiting, weight-loss, edema, anorexia); in Autologous BMT patients – (asthenia, malaise, diarrhea, rash, peripheral edema, urinary tract disorder); and in Allogeneic BMT patients – (abdominal pain, chills, chest pain, diarrhea, nausea, vomiting, hematemesis, dysphagia, GI hemorrhage, pruritus, bone pain, arthralgia, eye hemorrhage, hypertension, tachycardia, bilirubinemia, hyperglycemia, increased creatinine, hypomagnesemia, edema, pharyngitis, epistaxis, dyspnea, insomnia, anxiety, high BUN, and high cholesterol).
  • If ANC > 20,000 cells/mm3 or if platelet counts > 500,000/mm3, LEUKINE administration should be interrupted or the dose reduced by half. Twice weekly monitoring of CBC with differential should be performed.
  • Leukine therapy should be discontinued if disease progression is detected during treatment.
